How to prepare for your data science interview questions?

Before the interview, you must keep these things in mind-

Research for the role and identify your fit

Read the entire job description and look out for the exact fit for yourself. Also, consider what roles and responsibilities you will be assigned or be in charge of. With a clear idea, you can predict the questions and the topics covered in the interview.

Getting an exact idea of what an interviewer is looking for

Sometimes an interviewer is looking for a hard, technically skilled person to start right away, whereas others are looking for soft skills and critical thinkers so that they know they can train them on specific tools.

Tell them your ideas even if you don’t know how to execute them. These can show that you have strong critical thinking ability and a knack for providing innovative solutions to diverse problems.

Be honest about your technical skills.

Of course, you want to present yourself well in front of the interviewer but never lie about or overly embellish your technical or software skills. Avoid blindly saying yes to anything. For example, if the interviewer asks about regression and you are unfamiliar with the term, then you won’t be able to answer about linear regression.

Ask them about the team you will be working with

Surrounding yourself with people who can motivate you and help you grow is important. So, ask them about the team you will be working with and your supervisors. Because finding a work environment or the right people who will push your boundaries, and challenge you in every step is very important to grow in your career.

Do not hesitate to ask any questions that you may have with regards to the job position that you are applying for. It shows that you are responsible, how keenly you have researched the company, and how excited you are to join them. 

You can ask questions like-

• What would a typical day at work look like?
